Under PressureSolve the riddle of the Ruins

Grim ReaperHarvest all available civilians in the Alien Campaign

(MISSABLE) - During the Alien Campaign there are several civilians marked with a Green Aura. Once you have escaped the Research Lab you will be able to summon facehuggers to harvest them. This is accomplished by pressing while facing them.

Like the other 2 Nightmare difficulty trophies this is the hardest SP Alien trophy. You must beat the Alien campaign on the hardest difficulty without any checkpoints.

The Alien, unfortunately, is the most difficult of the 3. As always, take it slow, you are not on a time limit. Use your stealth and hide in the shadows to avoid being seen. Using to hiss helps immensely.

I Like to Keep This HandyKill 2 enemies with one shot with the shotgun

The easiest places to get this trophy are in the Research Lab or the Refinery.

Research Lab: Right after activating the controls and getting ready to head outside for the first time. You will hit a walkway where you will be ambushed by two Aliens in very close quarters. Position yourself to hit both. If you fail, reload.

Refinery: Right after getting the shotgun you will come to a bridge and be ambushed by several Aliens. Simply run around in a circle to get them to group together and once multiples of them are grouped begin to open fire. If you fail, simply reload.

Spin DoctorKill two enemies with one throw of the Battle Disc

Easier than it sounds. During the Ruins level you will hit a checkpoint right when your objective changes to hit the 3 switches. When you hit this point jump to the platform on your left and sneak behind the 2 marines there. Pull out your battle disc, position yourself so that both Marines are in one line, and let loose. If you fail, reload.

In general though this trophy is not as difficult as it would sound, and there are several other points this will work. Just remember to keep cloaked and that your Battle Disc works like a boomerang - it will kill going to and from you. As long as the Marines/Aliens are in a line and close together you can nail 2 in one throw easily.

GunslingerKill 30 enemies with the pistol

Very easy trophy, just time consuming.

My recommendation is to start the Marine Campaign on easy and during the first level there is a point you will hit where Aliens will begin to climb over a barricade. Simply pull out the Pistol at this point and start killing! The Aliens will spawn continually until you enter the elevator.

Persecution ComplexAchieve Persecutor status more then once in any Ranked Match

This is a rough trophy. To achieve Persecutor status you need to kill the SAME person 5 times without them killing you. You can still be killed by other people during this, but not the person you are trying to persecute.

I would recommend doing this with the Predator due to cloak and vision modes, although it's not required.

If you are having issues with this trophy, I would recommend boosting it with friends. Alternatively, make a thread here and ask for help.

Ain't Got Time to BleedHeal or regenerate 30 blocks of health in Survivor

Another easy trophy. Get into a Survivor match and use Stims () as you get hurt. It is 30 BLOCKS of health, not 30 times, so if you wait until you get down 2 bars and use it, you will only need 15 Stims.

As per Merceinarie_Ant, there is a very simple glitch to getting this. First off, I would recommend doing this disconnected from online. The 1.01 seems to affect the trophy, but how it is affect it isn't 100% obvious. In some cases your online rank is just "resetting," but you can still get the trophy just fine. Others are reporting trouble with the trophies entirely.

Either way, I would recommend not going online while you attempt this. Here is a good video-guide

The general idea is to connect to a ranked match, and as soon as you get to a point where it is looking for a match you back out to the main screen and go into the Marine campaign. Start the game from the first level and make it to the elevator after the barricade part. As soon as you get the checkpoint when going down the elevator, begin committing suicide by using the Grenade Launcher at your feet. After about 15-20 minutes you should have the 18060 xp.

If you choose to go "legit" for this trophy, it corresponds to 60-180 matches depending on your skill level and match. In my experience there doesn't seem to be a significant difference between individual matches. It's all about getting kills and bonuses
